Architecture split: Cloudflare Pages (static site), Worker (API + cron
scheduling), D1 (SQLite database), R2 (replays + JSON indexes, zero
egress) — all within the free tier with 95%+ headroom on every quota.
Rackspace Spot handles match workers, bot containers, and the evolution
pipeline — all stateless and interruptible. Includes D1 schema, Worker
cron design (matchmaker, indexer, health checker, reaper), R2 bucket
layout, free tier usage math, and graceful degradation model. Drops
infrastructure cost from ~$65-110/mo to ~$35-70/mo.
